Abstract: <PICT:0988479/C1/1> A batch composition for the production of foamed glass comprises 100 parts of glass, 1 to 20 parts of a blowing agent, aluminium in the form of fine flakes, and a binder.  A devitrifying agent, e.g. alumina, zircon, zirconia, titania, may also be added to the batch.  The preferred blowing agents are calcium or barium sulphates.  Glass foam is made by heating the above composition at 1750-2100 DEG  F. for 0.5-2.5 minutes.  The glass preferably has a viscosity of 1000-2,000,000 poises at 1750-2050 DEG  F. Specified glasses have the following composition:-(a) 54% SiO2, 14% Al2O3, 17.5% CaO, 4.5% MgO, 10% B2O3; (b) 53.5% SiO2, 14.2% Al2O3, 16.6% CaO, 4.5% MgO, 6.9% B2O3, 0.7% Fe2O3, 2.8% MnO, 0.8% TiO2. The binder may be carboxymethyl cellulose. The foamed glass may be made in the form of slabs or plates, but is preferably made as foamed pellets which may then be coated with latex and combined with a binder to form massive bodies.  In one embodiment, glass from a melter 34 is passed through water-cooled crushing rolls 36 to form cullet, which is ground together with the other ingredients in a ball mill 22.  The ground and mixed batch is supplied, together with water, to a pelletizer 24, and formed into pellets which are then passed through a screening unit 26, wherein they are sorted by graduated, slanted screens 84 into size ranges.  Pellets of the desired size ( 1/64 -\ba1/4 inch) are supplied from receptacle 96 to rotary drum 98 of a coating unit 28 wherein they are coated with a separating agent, e.g. talc.  The coated pellets are then placed in a charge hopper and trough 100 and fed to an inclined heating unit 30.  The unit comprises a rotatable insulated metal casing heated by a burner at its discharge end.  After preheating to 1500 DEG  F. in unit 30, the pellets are discharged down shoot 134 on to a conveyer belt in furnace 32 where they are foamed by heating to 1750-2100 DEG  F. for 0.5-2.5 minutes.  The pellets are annealed at the discharge end of the furnace and discharged into receptacle 152.  Foamed pellets having an open cell structure may be produced by reheating the pellets for approximately 5 minutes to the aforesaid foaming temperature.

Abstract: 1,011,749. Switching inductive loads. TELETYPE CORPORATION. June 5, 1962 [July 5, 1961], No. 21578/62. Heading H3T. A circuit for energizing an inductor in response to a signal provides a steady potential across the inductor while the current therein is increasing and then holds the current at a steady value when a predetermined magnitude is reached. The invention is described in connection with the selector magnet of a teleprinter which is to be controlled by signals having mark and space periods. In the space period transistor 11 is cut off by the absence of signal on its base, and transistor 15 is thus conducting. Transistor 19 is cut off by the voltage drop across voltage-sensitive resistors 30, 31. Transistor 48 is conducting, while transistor 60 is cut off by the voltage drop across 64. The input circuit of transistor 11 has ohmic resistors 25, 26 and voltage-sensitive resistors 27, 28 which are switchable to cater for different magnitudes and datum levels of the mark signal applied at 23. When a mark signal appears it turns on transistor 11 and cuts off transistor 15 through lead 16, thus reducing the voltage drop across 30. Transistor 19 now conducts and current is able to flow through the inductor 45 via transistors 48 and 19. As soon as this current starts, the base and emitter of transistor 60 go more positive to extents that enable this transistor to conduct; transistor 49 is then cut off since its base potential is maintained first by capacitor 73 and then by clamping diode 74 in conjunction with resistors 71 and 72. Thus the rising current through the inductor is carried by transistor 60 instead of 48. When, however, the emitter of 50 becomes sufficiently positive transistor 48 will conduct again and cut off 60, the inductor current now being through transistor 48 and high resistance 54. The circuit is stabilized during the period of rising inductor current by positive feedback through diode 57 which holds transistor 15 cut off. At the end of the "mark" period, the input signal cuts off transistor 11 and thus turns on transistor 15. The collector voltage of 15 is transferred via diode 65 to the base of transistor 19 and cuts it off (together with diode 55), thus opening the path of current through the inductor. The back E.M.F. across the inductor causes diodes 55 and 66 to conduct and drives the collector of 19 and the base of 15 more negative via diode 57, ensuring that the latter is held conducting. During this changeover period transistor 48 remains conducting and transistor 60 remains cut off. NPN transistors can be used instead of PNP. The voltage-sensitive resistors 27, 28, 30, 31 act as current-limiters for surges and provide a fixed voltage drop; they comprise PN and NP junctions in parallel. Specification 556,700 is referred to.

Title: Signal to noise ratio enhancement using baseband signals in an fm television system
Inventor: MOBLEY JOSEPH G II
IPC: H04N5/44
Filed: 1985-11-07
Abstract: In an FM television signal angle modulated with luminance and chrominance information, there exists a high degree of correlation between picture elements occurring one line period apart. In an effort to steer the pass band of a tunable bandpass filter to the instantaneous frequency of the incoming television signal, a steering signal is developed which utilizes this high degree of correlation. For NTSC systems, luminance information is delayed by one-line period (63.5 us in the U.S.A.) and combined with suitable delayed chrominance information to form the filter's steering signal. For MAC systems, one-line delayed luminance and two-line delayed chrominance information are alternately applied to the filter as its steering signal. By steering the pass band of the filter to the incoming signal, maximum signal will be captured with minimum noise, enhancing the signal-to-noise ratio of a color television system.

The polycrystalline material has a first region substrate surmounted by a terminal region stratum which is integral with the first region. The terminal region stratum which is harder and of denser, finer crystalline structure than the first region substrate and is formed in a reaction stage subsequent to the reaction stage in which the first region of polycrystalline material is formed. Growth of the first stage is attained by by attenuating or interrupting the transport of molten parent metal to the first region under conditions which nonetheless leave or maintain therein enough oxidizable molten parent metal to form the polycrystalline material of the terminal region.

Granted: 2011-06-22
Abstract: An internal combustion engine includes an advanced vehicle system controller (VSC) that calculates a total power demand to meet a driver wheel power demand plus any accessory loads and independently schedules an engine speed and load operating point to meet the total power demand. A reduction in available engine brake power that is not associated with a driver input, and would ordinarily cause the VSC to respond by raising engine speed, is detected. The driver wheel power demand is reduced to compensate for the reduction in available engine brake power such that the VSC does not need to raise engine speed to meet the driver wheel power demand. A magnitude of the reduction may be determined according to a calibration map to allow a trade off to be made between driveability and noise, vibration, and harshness.
